BACKGROUND

Cancer is a major worldwide public health problem; in the United Statesalone, approximately 574,000 people died of cancer in 2010. See, e.g.,U.S. Mortality Data 2010, National Center for Health Statistics, Centersfor Disease Control and Prevention (2010). Many types of cancer havebeen described in the medical literature. Examples include cancer ofblood, bone, skin, lung, colon, breast, prostate, ovary, brain, kidney,bladder, pancreas, and liver, among others. The incidence of cancercontinues to climb as the general population ages and as new forms ofcancer develop. A continuing need exists for effective therapies totreat subjects with cancer. Breast cancer is one of the most commontypes of cancer, especially among women. In the United States, it isestimated that there will be about 230,000 new cases of breast cancerand about 40,000 deaths from breast cancer in 2012. See, e.g., BreastCancer Statistics, National Cancer Institute (2012), available atwww.cancer.gov. Among different types of breast cancer, triple negativebreast cancer (estrogen receptor(ER)/progesterone receptor/HER-2negative) is more aggressive than other breast cancer subtypes. Notargeted therapy exists for triple negative breast cancer. Triplenegative breast cancer has a higher rate of recurrence resulting indeath, although the tumors initially appear to respond to chemotherapy.Clearly there is a need to develop effective targeted therapy for triplenegative breast cancer.

Changes in protein synthesis are directly linked to multiple humancancers. Translation initiation is deregulated in many cancers,including, e.g., lymphoma, breast cancer, head and neck cancer,colorectal cancer, lung cancer, bladder cancer, cervical cancer, andprostate cancer. Many proteins supporting the high rate of cancer cellgrowth, proliferation, and survival are translated from mRNAs havingsecondary structures, which have a greater dependence on rate-limitingtranslation factors such as eukaryotic initiation factor 4E (eIF4E).eIF4E overexpression in tumors can be a predictor for relapse in breastcancer regardless of nodal status and for drug resistance to adjuvantchemotherapy. A high percentage (>60%) of triple negative breast tumorsexpress high levels of eIF4E. The patient group with high levels ofeIF4E has a 1.6-fold higher rate of recurrence and a 2.1-fold increasein relative risk for cancer death. High levels of eIF4E drive thetranslation of proteins responsible for cancer initiation andprogression resulting in aggressive phenotypes and enabling the tumorsto better survive radiation treatment and chemotherapy. Therefore, it isdesirable to regulate protein translation in cancer, in particular,inhibit the rate-limiting steps in protein translation in order tocontrol cell growth and proliferation.

eIF4E, the rate-limiting factor for eukaryotic protein translationinitiation, is ubiquitously expressed in multiple breast cancer celllines. The activity and availability of eIF4E are controlled, e.g., bybinding proteins such as 4E-BP1. The activity of these binding proteinsis in turn regulated by phosphorylation, particularly by mTOR. eIF4Eover-expression along with the concomitant enhanced translationinitiation drives cellular transformation and tumorigenesis. eIF4E is aconvergence point for many oncogenic pathways and a key factor formalignancy in human cancer tissues and in experimental cancer models.Enhanced translation initiation is found in malignant breast phenotypes.eIF4E over-expression leads to breast carcinoma angiogenesis andprogression. eIF4E elevation of 7-fold or more is a strong independentprognostic indicator for breast cancer relapse and death inretrospective and prospective studies. Antisense oligonucleotide therapydown-regulating eIF4E resulted in a reduction of in vivo tumor growth inPC-3 prostate and MDA-MB-231 breast cancer models in mice. No toxicitywas observed when 80% knockdown was observed in essential organs,suggesting tumors are more sensitive to translation initiationinhibition than normal tissue.

Translation initiation factor eIF4E and its binding protein 4E-BP1 aremajor downstream effectors of the PI3K/Akt/mTOR pathway. mTOR and othermembers of the PI3K/Akt/mTOR family control the establishment andmaintenance of cancer phenotypes. The PI3K/Akt/mTOR pathway has beenclinically validated as a target for cancer therapies. Overactivation ofPI3K and Akt is found in a wide range of tumor types. PI3K catalyzes theproduction of phosphatidylinositol-3,4,5-trisphosphate. This lipidactivates Akt protein kinase, which in turn triggers a cascade ofresponses ranging from cell growth and proliferation to survival andmotility. PTEN, a dual specificity phosphatase, is an inhibitor of thePI3K pathway. Second to p53, PTEN is most frequently mutated or deletedin human tumors. Several PI3K inhibitors have been developed in clinicaltrials. mTOR controls translation initiation through phosphorylation andinactivation of 4E-BP binding protein, thereby activating eIF4E.Activation of eIF4E is required for the translation initiation of mRNAsthat have long structured ′5-untranslated regions. Increasing evidencesuggests that mTOR, as a central regulator of cell growth andproliferation, controls protein biosynthesis. The mTOR pathway controlstranslation of mRNAs encoding proteins such as cyclin Dl, c-Myc, andornithine decarboxylase that are essential for G1 cell-cycle progressionand S-phase initiation. Inhibition of mTOR results in G1 cell cyclearrest. Rapamycin, an mTOR inhibitor, has significant antitumor activityagainst many tumor cell lines in the NCI screening as well as in humans.However, formulation, solubility and stability issues have hindered thedevelopment of rapamycin. Analogs of rapamycin have been developed toaddress these issues and have shown promising results in Phase II/IIIclinical trials. There remains a need for alternative cancer therapeuticagents that are effective and safe, e.g., agents having maximuminhibition of tumor growth, minimal toxicity to normal cells, andminimal on-target side effects in the treated subjects.

Excessive and persistent activation of cells characterizes both cancerand fibrotic diseases. Fibrosis is the formation of excess fibrousconnective tissue in an organ or tissue in a reparative or reactiveprocess, which can be benign (e.g., wound healing) or pathological. Theterm fibrosis is often used to indicate a pathological state of excessdeposition of connective tissue, which can lead to loss of function andorgan failure. During wound healing myofibroblasts are specialized cellsthat acquire smooth muscle features (including t-smooth muscle actin)and are important contributors to tissue repair. Myofibroblasts can bederived from fibroblasts, epithelial cells, and endothelial cells andare characterized by their ability to secrete extracellular matrix.Regardless of their origin, TGF-β is the principle growth factorresponsible for differentiation to the myofibroblast activated phenotype(J L Barnes, Y Gorin, Myofibroblast Differentiation During Fibrosis:Role of NAD(P)H Oxidases, Kidney Int. 2011, 79: 944-956). During normaltissue repair myofibroblasts are activated in a controlled and transientmanner (Hinz B. et al., Recent developments in myofibroblast biology:paradigms for connective tissue remodeling, Am J Pathol. 2012,180:1340-55). However, excessive and persistent activation ofmyofibroblasts plays a key role in both fibrotic disease and cancer. Infibrotic disease, large numbers of myofibroblasts accumulate and areresponsible for the uncontrolled production of extracellular matrixwhich leads to loss of function and organ failure. Fibrotic diseasesinclude a variety of clinical entities, including organ specificfibrosis (heart, liver, lung, kidney, bone marrow, skin, pancreas),other forms of fibrosis (retroperitoneal, nephrogenic, and cystic), andconnective tissue disorders (atherosclerosis, cirrhosis, scleroderma,keloids, Crohn's disease, and endometriosis). In cancer, the tumorstroma microenvironment contains large numbers of myofibroblasts as wellas other cells, which are collectively referred to as cancer associatedfibroblasts. Cancer associated fibroblasts play a major role in tumorinitiation, progression, and metastais through the production of avariety of growth factors, ECM proteins, and other pro-angiogenic andpro-metastatic factors (Khamis Z I, et al., Active roles of tumor stromain breast cancer metastasis, Int J Breast Cancer, 2012, 2012:574025).

Therefore, drugs which inhibit the transition of fibroblasts tomyofibroblasts have potential for the treatment of cancer, theprevention and treatment of metastatsis, and the treatment of a varietyof fibrotic diseases.

Animals were housed 10 mice per cage in micro-isolators, with sterilecorn cob bedding, food, and water. Mice were acclimated for 3 days andgiven food and tap water ad libitum. Animals were examined prior toinitiation of the study to assure adequate health and suitability.Animals that were found to be diseased or unsuitable were not assignedto the study. During the course of the study, 12-hour light/12-hour darkcycle were maintained. A nominal temperature range of 20-23° C. with arelative humidity between 30% and 70% was maintained. LabDiet5053-certified PicoLab Rodent Diet and sterile water were provided adlibitum during the study.

Exemplary Protocol: Ten mice per group were inoculated s.c. on the leftflank with 5×10⁶ MDA-MB-231 cells. When tumors reached a mean volume ofapproximately 100 mm³, animals began treatment with a compound providedherein (See Table 5). Test article or vehicle were given once daily byIP injection for up to 31 days. Tumors were evaluated every Monday,Wednesday and Friday, body weights and condition were evaluated on adaily basis.

Cell Culture: MDA-MB-231 breast cancer cells were grown in Liebowitz'sL-15 with 10% fetal bovine serum and 1% pen/strep. Cells were routinelytrypsinized and passaged 1:3. On the day of implantation, cells werewashed in PBS, trypsinized and resuspended in complete media. Cells werewashed 3x in serum free media (centrifuged 1000 rpm for 5 min). Cellswere resuspended to a density of 1×10⁸ cells/mL and diluted 1:1 withMatrigel. Cells were implanted s.c. using a 23G needle in a volume of0.1 mL.

Tumor Measurement: Tumors were monitored daily. If, during a dailyevaluation, an animal's tumor appeared to have exceeded 1500 mm³, thetumor was measured; and animals with tumors greater than 1500 mm³ and/orthat had become necrotic and/or hindered movement were euthanized.Tumors were measured twice weekly by measuring each tumor in 2dimensions, along the largest dimension (length, L) and perpendicular tothis dimension (width, W). Tumor weights were calculated using thestandard formula: (L x W²)/2. The mean tumor weight and standard errorof the mean were calculated for each group at each time point. An ANOVAwas used to compare differences of primary tumor volume.

Animal Weight: All animals were weighed twice weekly throughout thestudy. Group weight change was expressed as a daily group mean weight.Animals that lost greater than 20% of their total starting body weightwere euthanized.

In one embodiment, Compound 1 was dosed in mice at a dose of, forexample, qd 50 mg/kg, and the dose was reduced to 25 mg/kg on day 7. Inone embodiment, mean tumor volume at Day 31 for the vehicle group was898±260 mm³, while mean tumor volume at Day 31 for the group of micetreated with Compound 1 was 276±119 mm³. In one embodiment, mean weightgain for the vehicle group was 4.2%, while mean weight gain for thegroup of mice treated with Compound 1 was 0.1%.

On day 32, the group of mice treated with Compound 1 was subdivided into2 groups. For the next 10 days, one group continued to receive treatmentwhile the other did not. In one embodiment, tumor growth did not resumewithin 10 days of the withdrawal of Compound 1.

At study termination, mice still undergoing treatment were given a finaldose of compound and sacrificed 2 h later. Average concentrations ofcompounds in plasma and tumor were determined. In one embodiment,detectable levels of Compound 1 were found in both plasma and tumorsamples from the mice that discontinued treatment on Day 31, indicatingthat less frequent dosing of Compound 1 will likely be an option.

In one embodiment, a triple negative breast cancer xenograft(MDA-MB-231) was performed on Compound 1 and Compound 2 dosed IP and PO.Mean tumor volumes over time were calculated from length and widthmeasurements. Treatment was initiated when average tumor size reached100 mm³. Compound 1 and Compound 2 were dosed at 50 mg/kg IP and 100mg/kg PO. Doses were either skipped or cut in half for those mice thatlost >15% of their body weight. The tumor growth inhibition data issummarized in FIGS. 3-6 and Table 6.
